酶解法辅助提取花椒油树脂的工艺优化

试验以纤维素酶法辅助优化提取花椒油树脂。通过利用单因素和正交试验分析,结果表明,酶解温度为影响提取效果的显著因子,优化后提取条件为酶用量2.0mg/100mL,酶解时间1.5h,酶解温度45℃,在该工艺条件下提取一次花椒油树脂的平均提取率为30.2%。验证试验表明,经酶解提取法提取花椒油树脂与未经酶解处理的乙醇浸提法相比,结果增长25.8%。     

花椒挥发油与其主要成分经皮促透作用的比较研究

研究目的：比较花椒挥发油与其主要成分作为经皮促透剂的皮肤细胞毒性,对系列不同油水分配系数药物促透作用特征及其作用机制。 创新要点：选择系列不同油水分配系数中药活性成分简化并表征中药制剂中复杂有效成分,对比研究花椒挥发油与其主要成分的经皮促透作用特征差异。 研究方法：利用表皮角质形成细胞（HaCaT）和真皮成纤维细胞（CCC-．ESF-1）测定其皮肤细胞毒性,选择系列不同油水分配系数中药活性成分作为模型药物测定花椒挥发油与其主要成分的经皮促透作用特征差异,并在此基础上采用傅利叶变换红外光谱（FTIR）等研究其促透作用机制。 重要结论：花椒挥发油相对于其单一组成成分具有更好的经皮促透效果。

Cytotoxicity and enhancement activity of essential oil from Zanthoxylum bungeanum Maxim. as a natural transdermal penetration enhancer简

The aim of this present study is to investigate the effect of Zanthoxylum bungeanum oil (essential oil from Z. bungeanum Maxim.) on cytotoxicity and the transdermal permeation of 5-fluorouracil and indomethacin. The cytotoxicity of Z. bungeanum oil on dermal fibroblasts and epidermal keratinocytes was studied using an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The rat skin was employed to determine the percutaneous penetration enhancement effect of Z. bungeanum oil on hydrophilic and lipophilic model drugs, i.e., 5-fluorouracil and indomethacin. The secondary structure changes of the rat stratum corneum (SC) were determined using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), and saturated solubilities and SC/vehicle partition coefficients of two model drugs with and without Z. bungeanum oil were also measured to understand its related mechanisms of action. It was found that the half maximal inhibitory concentration (IC₅₀) values of Z. bungeanum oil were significantly lower in HaCaT and CCC-ESF-1 cell lines compared to the well-established and standard penetration enhancer Azone. The Z. bungeanum oil at various concentrations effectively facilitated the percutaneous penetration of two model drugs across the rat skin. In addition, the mechanisms of permeation enhancement by Z. bungeanum oil could be explained with saturated solubility, SC/vehicle partition coefficient, and secondary structure changes of SC.
